Water pooling on rubber roof
I have a relatively new rubber flat roof. I notice that water pools in numerous locations about 10-20 feet from back of house. (Drains towards rear) Will this pooling create problems when it ices up or compromise the rubber or its seams? The contractor swears up and down it is fine and to think of…

The contractor swears up and down it is fine and to think of swimming pools and how they hold water year round.
They are bugs that make a lot of noise at night.

what are “crickets”?
Original Poster,
I hope this eases your mind a bit.
Through my own personal experience I have to agree with the previous comment. (6:59) I’ve got to laugh about this too.
We had our flat roof (Rubber) done by a friend of mine in the spring of 1999. He is a NYC Fireman and does flat roofing on the side.
My wife was concerned about hiring him. She felt that we should hire a lisenced roofer to do the job. We wound up giving the job to him.
I never paid much attention to my flat roof before. But just to please my wife, I went up on the roof a couple of weeks after the job was completed. I noticed several ponding areas toward the back of the roof. And in the winter they stay for several days, espesialy when the water freezes. Two of them were rather large and I became concerned about them. (my roof drains to the rear also) My friend told me that most flat roofs have some ponding on them. He also told me not to worry.
More than eight years have past and my friend The Fireman indeed have to come back twice to repair leaks. But NIETHER one of the leaks were toward the back of the roof. Both times they were way up toward the front of the house.
How do you figure. 🙂
Mabee the swimming pool analogy is not so far fetched after all.
I would’nt woory about it at all.
ENJOY THE HOLIDAYS!!
Our house is an attatched brownstone. Our roof also has several ponding areas on it. It’s been that way for years now and we have never had a problem with it. BTW all of my nieghbors roofs have ponding on them also. It appears as if that’s common. If your roofer is reputable and guaranties it you need not worry.
OP, who is your roofer? I’m curious because we put in a new rubber roof too and our roofer also says pooling of water is not a problem. Which sounded ridiculous to me. We have pooling only in one area, but it doesn’t seem to be drying out within 48 hours so I’m concerned about it.
I dunno– roofs are supposed to shed water, not collect it. Think of a swimming pool–when you’re building a swimming pool.
Anyplace water is allowed to sit long enough, sooner or later it’s going to find the path of least resistance into your house.
With rubber roof should not matter. We have one upstate with plenty of standing water (and of course now snow).
If you have the guarantee from the establisheed roofer…no problem.
As the previous poster commented, it’s a major problem if the water doesn’t evaporate within 48hrs. A good roof installation shouldn’t have pooling at all, but it is difficult for most roofers to get the drainage slope 100% correct when accounting for the seams. Spots that take longer will cause the roof to sag in those spots eventually and in the winter time the ice won’t help. If it is a major problem the roofer should either redo their work, or at the least install ‘crickets’ which will add an additional slope to the problem areas, draining the water to spots on the roof that do drain properly, such that gravity does the rest.
The rule of them is that if it evaporates in 48 hours it is probably okay, but if the pool is large enough that it could sit there for more than that, well… It still might be okay for many years but it will eventually lead to leaks faster than the rest of the roof.
